I am going to build a power bleeder that is slightly different
from all mentioned so far. Since I have a small compressor with
an air tank of about 10 or maybe 20 gallons I will use it as
a pressurized air source. I will have a bottle made of hard plastic
transparent and about 2 liter capacity. There will be two hose
fittings on the cap. One connected to the compressed air source. The
other connected to the cap of the brake fluid reservoir cap with a
fitting on it too.

Internal to the 2 liter bottle one of the fittings will have a hose
reaching the bottom of the bottle but the other does not have a
hose inside. This 2nd one will be connected externally to the
compressor. The 2 liter bottle will be filled with fresh brake fluid.

The air compressor will be set to 10 or 12 PSI and holds it there.
I hope this bleeder is easier to use because I will not have to
empty the (pressurized bleeder) after bleeding. The 2 liter bottle
will keep the remaining brake fluid in it after bleeding. The
compressor will be free from brake fluids. I can drain down the
pressure of the air tank before disconnecting the bleeder.

I do have to visit Home Depot for hose fittings. The cost will be
less than $10 I think since I already have the small compressor.

Has anyone tried this? Will this work? I hope so.
